I should emphasize that I'm not trying to call anyone crazy, I'm using "psychosis" in a formal sense to talk about someone's connection with reality

I certainly hope that this world will never come to a state where you can not call the crazy people crazy...

but on a slightly more ontopic note, whats the easiest way to calculate square waves duty cycle in ltspice?

Isn't it 50% by definition :P

not by mine

I have a square wave safe space here, where they can be all kinds of frequencies and duty cycles they like

@PlasmaHH I feel like the word "crazy" is already ruined, along with most words used by laymen

They skew the meaning so deeply, that if you use very exact vocabulary, it's ineffective even with intellectuals, because they need to clarify if you intend the popular meaning or the actual meaning

That's "newspeak" if I ever observed it

hm, where do I have that photo of someone in a library putting a 2016 sticker over the 1984 copies...

On the pin width of this part, what do the letters A, B, C and the M in a circle mean?

I suspect I am missing some important contextual information needed to understand the details of the drawing.

does another datasheet contain more information? i.e. refers to A,B,C?

@PlasmaHH If so I wouldn't know what data sheet that is.

There doesn't appear to be any information in the document linked telling the reader where to find the meanings of the letters.

So, I thought they might be something standard that I should know.

well, it seems that htis is a generic "package outline datasheet" that is referred from other datassheets of chips using that actual layout

@PlasmaHH Ah yes, that is true. One moment.

Ok for the record, here is the datasheet for the actual part.

is it just my badly calibrated monitor or do these actually look black while the others are gray?

@PlasmaHH These what?

these ABC measurements

I don't think I see a difference.

ok, I blame the monitor then

Anyway, the part datasheet in section 4 says to go look up that other document with the drawings. That's it. No definition of A, B, C, etc. Still looking though...

Nah, the only other drawing in the part datasheet is the pinout, no geometric info.

I want a high bandwidth short range wireless transceiver to communicate remotely with a powerful MCU. What is the best solution that money can buy (it has to be portable)?

Define "high" bandwidth.

define short range

Define "want".

300 mit per second short range 10 meters

mbit*

it has to be bidirectional sending and receiving data back and forth continuously

now we need a definition for "best" since obviously the obvious solution of wifi doesn't work

I'm fine with Wifi but chips like ESP8266 are too weak

so chose any other? from the current requirements all >300MBit are equally good

So I want something like WIFI to SPI so It can communicate directly with the MCU

@DanielSank I'm guessing A and B are datum surfaces(?) from which other measurements are refrenced/

@ThePhoton did you look at the drawing?

@PlasmaHH Yes I'm looking for "any other" what solutions do you have in mind ?

300MBit SPI?

@DanielSank Yes, but I'm not expert at interpreting mech drawins

I don't have any in mind, I would chose some technology and then look what the supplier of my choice has available

I thought of attaching a router but what would be the ideal protocol to use for interfacing it with the MCU?

@DanielSank engineering.pages.tcnj.edu/files/2012/02/…

whatever protocol that the chip uses?

M in a circle indicates maximum material condition.

@ThePhoton Thanks!

I'm a software engineer so I'm not very familiar with the available lower end protocols that would be ideal for such data rate. @PlasmaHH suppose I have full control on what the chip uses what would you choose for 300mbits?

@codinginsane For 300 mbits (millibits), a guy waving flags would work fine.

*Mbps

@codinginsane I am not sure if you are up to the task then, doing your own pcb at these speeds isn't trivial. I would probably chose ac or maybe play with ad, depending on parts availability. then just go to digikey or whatever and look whats there.

@DanielSank Definition of A, B, and C is where it shows that those refer to specific planes (the top side, the right side, and the bottom side) of the part

@ThePhoton I don't see it...

ohhhhhhhhhhhh

@DanielSank also gdandtbasics.com/feature-control-frame

I should probably throw more books at the problem and see what happens :)

No I still don't get it.

I see now that there are little labels on the top/left drawing showing A and B referring to planes.

I still don't understand what the letters mean on the other drawings.

@ThePhoton Super useful!

Those define A and B.

Yeah, I saw that.

Then some other features there's boxes that say "the location of this feature has tolerance X.XX relative to A, B, and C.

@DanielSank Ping

Ah, suddenly this all makes sense.

both relative to C?

That second link is totally crucial, thank you @ThePhoton.

@PlasmaHH c is always relative.

TE Cooler modules --- Is the "hot side" the side that the TEC will cause to heat up when I put positive current through it, or is it the side that's meant to be attached to a hot part that will be cooled down when positive current is run through the TEC? Somehow I seem to have gotten myself confused about this very basic question.

Final Year university project? Really?

@Asmyldof Maybe he's a music major?

@ThePhoton Hot side of a TEC is always the side that is receiving pumped heat through the TEC

@Asmyldof That's what I thought....why does my stuff seem to pump heat the wrong way?

@ThePhoton One can only hope, but one is very doubtful

@ThePhoton Bad childhood?

liberal arts major?

General ArtsnCrafts (retired) (D)?

I think I made too large a step

Something funny just occurred to me. @PlasmaHH identified parenthood as a reason to not have time for code reviews... but made that observation on an internet chat room. The irony is amusing.

@DanielSank you misunderstood it totally. I talked about reviewing multiple pull requests per day. that is totally different to spending the bit of free time I have the way I want.

Awww, let me be amused.

@PlasmaHH Not receiving 29kg packages

that reminds me of having to transfer something over wires

What's going on here?

@ThePhoton Imenna return a dish to my neighbours and possibly be gone for several whiles while they force-feed me coffee, but if there's TECissues, you can drop em here for me to review later

@0celo7 In short 1) Crap talking people as much as possible, 2) Particularly wussy liberals, 3) occasional discussion about electrical engineering.

@0celo7 beer and vacuum nanotubes. in that order

^ That too

@PlasmaHH Shame you never get past the first one

I like @PlasmaHH 's version much better.

What about liberals?

I do like the colors of this chat.

@0celo7 Oh, they like to feel victimized and render language useless.

whut, wait, it has colours?

Pull out the RED diffpair of your screen

@DanielSank The liberals in here or in general?

Scroll up for a wonderful description of everything wrong with wussy liberal crybabies.

@0celo7 I think in general, but I'm new around here.

Ah, I'm sure I will enjoy it.

@0celo7 Yes.

I was going to get coffee poisoning.

Considering physics' heavy communist bias, it will be a nice change of pace.

Ah right @PlasmaHH Wanted to say there's no rush

Also note that if someone asks a question on main, you should look for reasons to ridicule that person first, before answering the question.

Oh, and if someone asks you for advice, make sure to explain why your personal system is the best, even if it's orthogonal to what they're asking.

Got all that?

@DanielSank Where exactly was someone "ridiculed?"

@0celo7 Scroll up.

@DanielSank I already do that.

Maybe not orthogonal.

@0celo7 good.

But if it's 45 degrees or less, then definitely.

@0celo7 That's reasonable.

Notice that you want to emphasize shitting on people more than helping them.

@DanielSank Ok, calm down. Where did someone shit on you?

I read the transcript already.

I don't feel particularly uncalm...

I don't understand the coding lingo, so I must have missed it.

@Asmyldof the longer I wait, the higher the chance I forget it ;)

@0celo7 I heard its about coloured handkerchiefs in your jeans backpocket. brown in that case, one side passive and one side active. At least thats what I read, maybe its more modern, read it like 20 years ago

@0celo7 That's possible. Wanna start a discussion on contour integration just to see what happens?

oh btw. we should start typing slower, there are senior people ^^

@PlasmaHH eh?

@DanielSank you don't know the "type slower I can't read good" meme I guess

or maybe its called "elder people"? I am not sure, I always mess up english

@PlasmaHH senior, elder, all Good spores. LOL

@PlasmaHH Oh right, people with kids who can't do code reviews ;)

@Marla whats the terminus you people prefer? ;)

@DanielSank I mean people with grandchildren

@PlasmaHH. . anything except dead

lol

@PlasmaHH Ah, so negative time for code reviews.

@Marla hahah nice

@DanielSank no, more, I am looking forward to that time, all the fun with the kids, but you can give them back for the annoying time consuming stuff

I don't know why, but I suddenly feel reminded of one geography teacher I had...

she was arguing some really obviously stupid thing about glaciers...

was trying to emphasize her experience by something like "obviously I must be right"

to which the proper reply was "of course, you must have been there"

@PlasmaHH heehee

she was really really harmful to the students... like, when a hurricane goes over your house, only the outside walls are ripped of because of the storms eye...

@DanielSank I see your analysis and raise you a number theory

@MickLH ::shoots cloud of ink and jets away to safety::

@Asmyldof Turns out I had installed the TEC module upside down. Ho hum.

@ThePhoton This tends to happen once in a while

@ThePhoton I believe this is the leading cause of pumps going in the wrong direction

@MickLH Only non-coaxial pumps

@MickLH The other possibility is "got the wires crossed".

Or "extra factor of -1 in the control software"

Yeah but those are things you'd check for

@MickLH Nah, just re-cross the wires and move on.

You guys get "New York Ruby Frost" apples? Cause you should try them.

lol

so, anyone has an idea how to tackle my false vacuum decay project?

@ThePhoton farmers pay cornell U. fees for their IP to grow these apples :P

I feel like that should be all a TV commercial needs to say, I'd hate commercials way less if they just got straight to bragging about their R&D

@ThePhoton haz not. Send some!

@MickLH I'd hate commercials less if they'd just get to the point and not last so damn long sketching an unrealistic situation, so as to render TV time to an ad-watch interrupted by short bits of programming

That said, I haven't had commercials in my TV for years outside of 4OD and iPlayer

@MickLH They're pretty good. Not just super sweet like Gala or Fuji. More apple flavor.

Not sure if I like these better or Pink Lady.

Step 3: Profit?

@ThePhoton Step one does imply, just not really exactly to the same model

Or model owner
